Alarum Technologies confirmed the FBI seized additional domains belonging to its NetNut subsidiary. This follows an initial enforcement action on July 2, 2026.

The ongoing seizures are causing service disruptions across the proxy network. Management warns of a material adverse effect on operations and financial results if the situation persists.

Alarum is conducting an internal investigation into potential third-party misuse for malicious or unlawful purposes. The company pledged full cooperation with federal law enforcement.

The FBI is examining links between NetNut and software allegedly used to co-opt user devices. Alarum shares plunged in after-hours trading following the initial July 2 report.
